Deadly tsunamis threaten Puerto Rico, the Virgin Islands and the rest of the Caribbean and are an overlooked hazard in the region, geologists reported at the annual meeting of the American Geophysical Union here last week.

Many sit above a subduction zone, where two plates meet and one slides protestingly under the other, down into Earth’s mantle.
